Pipe Bedding 20 mm delivered in Reading
20 mm single size is a clean, high-void stone used for deep trench surround, soakaways and attenuation layers. With no fines it drains freely and does not slump into voids, so it is the default where the surround also has to store or convey water.
Into Reading and across South East we supply it loose by tipper, by grab lorry where a stockpile has to be loaded or reached over a boundary, or in bulk bags for plots a lorry can't discharge into. Grab, tipper and HIAB loads across Reading, Bracknell, Slough and Newbury. Timed windows for town-centre and live commercial sites; skips for fit-out and refurbishment work.

What shapes Pipe Bedding 20 mm supply in Reading
Drainage packages on Thames Valley commercial and residential groundworks around Reading take Pipe Bedding 20 mm in daily call-offs rather than one bulk drop, so bedding lands as each run is dug rather than sitting in the way. Access-limited plots and timed town-centre drops decide whether it arrives by tipper, grab or bulk bag. Where the same site is also producing arisings loaded by grab where a tipper cannot get alongside, we plan the removal and the delivery together so the lorry is not running one leg empty. The same routes serve Bracknell, Wokingham and Slough.
Questions we get asked
What void ratio should I design a 20 mm stone soakaway to?
Clean 20 mm single size is commonly designed at around 30% void ratio, but your drainage engineer should confirm the figure for the material and compaction assumed in the calculation.
Is 20 mm single size the same as 20 mm ballast?
No. Ballast is an all-in mix of stone and sand for concrete. 20 mm single size is a washed, clean stone with the fines removed and is not a concreting material.
Do you cover Slough and Maidenhead?
Yes, the whole Thames Valley corridor including Slough, Maidenhead, Bracknell and Basingstoke.
Material out as well as in, around Reading
Most deliveries into Reading pair with a removal: the lorry takes your arisings to a licensed facility and comes back loaded, so you pay for one movement rather than two.
